To all.whom it may concern:

Be it known that I, ARGYLE CAMPBELL, a citizen ofthe United States, residing at kChicagoin the county of Cook and State of Illiv nels, have invented a certain new and useful Improvement-in/Metallic Car- Roofs, (Case 'D,) of which the followings a speciiication.

My invention relates to metallic car-roofs.

l The object of my invention is to make such IO tively gsmallquantity o ymetal and which will be very strong vand rigid inconstrucv tion. v V Y It consists, essentially, in the use of a novel thesame o t ersupporting mem erstherefor and the covering-plates of met 1. It also :consists in'details of construction, which 'will 'be hereinafter more fully described and claimedy -as the'lspeciiication proceeds. l l

In the drawings,'F igure 1 is a plan view, partially broken away, of the car embodying my invention in its preferred form. Fig.` 2

en arged, showing. the details of construe'- tion of the ridge-pole.

applicable to any of the common forms of cars, such" as that illustratedin 2, vhaving sides 10, ends .11, and longitudinal reinforcing members 13 at the upper edges ofthe sides.

. of ridge-pole 14,. such as is illustrated 1n detail in Fig. 3, the same being in the form \of an inverted U; The lbottom of the U proper I or to of the inverted U 15 is vangularly in-` 4o eline from its middle to each side insubstantially the inclination of the car-roof which it is desired to form. The bottoms of the upright members of theinverted U have extending from them flanges 16j, substantially parallel to the inclined surfaces just described. The ridge-pole 14 thus formed y extends from end to end of the car, bein suitably secured to opposite ends 11 thereo Resting upon these flanges. 16,v just de' tending from the rid e o e to the members 13, heretofore descri e are rafters or hall-,

l are; secured tothe member-13,l heretofore described, by means of angle-ironsflQ` and. .bolts 4or rivets 20 and have upon theirupper ends angle-irons 21, secured .thereto by bolts or rivets 22. l Through 'the angle-irons 21 on opposite lrafters or half-earlines fand -the -vertical W'ebs of the ridge-pole are bolts 23, adapted vunder the-action'of threads 24 and nuts to rigidly secure all of the parts together, as shown in Fig. 3. Bythis construction .I- form a roof-frame com osed of the ridge-Eole,thehalf-carlines,andt eu per e sides and ends vof the car W cl1 is very'strong for a given depth Iof the caresand consequent weight ofmetal. The

center `construction servesto j give greaty scribed I spread a continuous roof-plate-27,

extendingIrom end to end of the car/and meeting theopposite roof-plate-atthe apex of the ridge in line 28,` as shown. Over thisline 2 8- or break between the roof-plates upon opposite sides of the car I place an an- `g'ular cover-plate 29 and secure it to the roOf-plates-27 and the 'top 15' of the inverted .U by means of the bolts vor rivets 30. It p only needs an inspection of the drawings to It `should ybe understood that my roof is anylirluid top ass into said Open ine 28,-a'nd that s Ould any liquid so reach this lineof opening 28 it will be prevented from gettinfg,

into the car itself by the fact that the roo plates 27 have such a broad bearing upon the uprper portion 15 of the ridge-pole. f ,i he upper ed es of the roof-plates27- are bent over the e ges of the car-.frame in the doWnWardly-extendin portions 32, so that tlhiere` is no leak into t e car at theedges of t e car. f 1.

4By this complete construction I obtain a y very rigid car-roof and one in which'the sur-v face ,being made in only twopartsand the one joint therein thoroughly spliced is enconilitions.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a car, in combination with the sides les. andends of a car; a ridge-pole'in the form of an inverted U extending from end to end of y lthe car, there being anges upon the lower edges of the sides of said U, rafters r halfcarlines resting upon said llanges onopposite sides of the ridge-pole,`.means for securlng the'inner ends of said rafters to said ridgepole and means for securing the outerends lof said rafters tothe sides of the car.

2. In a ear, in combination With the sides and ends of a car; a central ridge-pole eX- tending from end to end of the car, the same in the form of an inverted U and havbein in -anges extending from its lower edges,-

ra ters or half-carlines resting` upon the flanges of said ridge-pole rigidly connected nesses.
